  1. Preheat oven to 400 degrees F (200 degrees C). Grease an 8x10-inch baking dish.
  2. Melt 6 tablespoons of butter in a large skillet over medium heat, and cook and stir the onion until soft, about 6 minutes. Mix in the zucchini, and cover the skillet; cook until tender, about 10 minutes. Stir in the kosher salt, black pepper, and parsley, and cook uncovered for 5 more minutes. Stir in flour, and reduce heat to a simmer.
  3. Mix the hot milk and chicken bouillon granules together in a small bowl, stirring until the bouillon has dissolved. Pour the milk into the skillet, and bring to a simmer, stirring constantly until the milk thickens into a sauce, about 5 minutes. Pour the zucchini mixture into the prepared baking dish. Sprinkle with Cheddar cheese. Mix the bread crumbs with 1/2 cup of melted butter, and sprinkle the crumbs over the casserole.
  4. Bake in the preheated oven until the casserole is bubbling and the top has browned, about 20 minutes.

I give it five stars with the adjustments I made. After reading other reviews, I left out the salt in the mix. And rather than mixing the bread crumbs with half a cup of butter, I just mixed the...

I have had this recipe for only about a month and I have made it several times even for our Thanksgiving gathering and my family loves it.

Delicious! I made it pretty much exactly as directed, and it turned out great! Creamy and cheesy and perfect!

This dish is awesome and easy to put together for even a beginner like me. I left out salt and only olive oil to saute veggies. No butter just bread cubes and cheese mixed.I only had Mozzarella...
